Colleyville Heritage HS's Football Field is set in the Colleyville suburban landscape of the Dallas-Fort Worth metroplex, with oak, cedar, and elm as the main surrounding tree pollen sources. Cedar is a particularly intense local source from December through February, while surrounding Texas prairie grasslands contribute substantial grass pollen and the flat open landscape allows wide dispersal throughout this northeast Tarrant County suburban school.

Does pollen in Colleyville come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Colleyville based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Colleyville, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
